Accurate Multi Panel Drug Urine Test Cup offers any combinations from 2 to 15 drugs of abuse tests but only

one cutoff concentration under same drug condition will be included per device. It is for in vitro diagnostic

use only.

The tests may yield positive results for the prescription drugs Buprenorphine, Nortriptyline, Oxazepam,

Secobarbital, Propoxyphene, and Oxycodone when taken at or above prescribed doses. It is not intended to

distinguish between prescription use or abuse of these drugs. Clinical consideration and professional judgment

should be applied to any drug of abuse test result, particularly in evaluating a preliminary positive result.

The tests provide only preliminary results. To obtain a confirmed analytical result, a more specific alternate

chemical method must be used. GC/MS or LC/MS is the recommended confirmatory method.

8. Device Description

Accurate® Multi Panel Drug Urine Test Cup are immunochromatographic assays that use a lateral flow

system for the qualitative detection of Amphetamine, Buprenorphine, Secobarbital, Oxazepam, Cocaine, 2-

ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine, Methamphetamine, Methylenedioxymethamphetamine,

Morphine, Methadone, Oxycodone, Phencyclidine, Propoxyphene, Nortriptyline and Marijuana in human

urine. Each Accurate® Multi Panel Drug Urine Test Cup device consists of a test cup and a package insert.

Each test cup is sealed with desiccant in an aluminum pouch.

10. Test Principle

Accurate® Multi Panel Drug Urine Test Cup is a rapid test for the qualitative detection of Amphetamine,

Buprenorphine, Secobarbital, Oxazepam, Cocaine, 2-ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine,

Methamphetamine, Methylenedioxymethamphetamine, Morphine, Methadone, Oxycodone,

Phencyclidine, Propoxyphene, Nortriptyline and Marijuana in urine samples. They are lateral flow

chromatographic immunoassay. When urine sample is added to the cup device, urine is absorbed into the

test strip and migrates upwards by capillary action. If the concentration of target drug presented in the

urine sample is below the cutoff level, the target drug will not saturate the binding sites of its specific

monoclonal antibody-coated particles. The antibody-coated particles will then be captured by

immobilized drug-conjugate and a visible colored band will be formed on the test line region. If the

concentration of target is beyond the cutoff level, the target drug will saturate the binding sites of its

specific monoclonal antibody-particles, thus the antibody-coated particles will not be captured by

immobilized drug-conjugate hence no colored band will be formed on the test line region.

A band should be formed on the control line region regardless of the presence of target drug or metabolite

in the sample to indicate that the tests have been performed properly.

f. Effect of Urine Specific Gravity and Urine pH

To investigate the effect of urine specific gravity, urine samples with specific gravity from 1.000 to

1.035 were spiked with target drugs at +50% cutoff and -50% cutoff levels. Three operators tested

samples using test devices from three different lots. The results were all positive for samples at

+50% cutoff and all negative for samples at -50% cutoff, indicating that urine specific gravity

between 1.000 and 1.035 has no effect on the accuracy and precision of the test device.

To investigate the effect of urine pH, urine samples with pH value from 4 to 9 were spiked with

target drugs at +50% cutoff and -50% cutoff levels. Three operators tested samples using test

devices from three different lots. The results were all positive for samples at +50% cutoff and all

negative for samples at -50% cutoff, indicating that urine pH value between 4.0 and 9.0 has no

effect on the accuracy and precision of the test device.

2. Comparison Studies

The method comparison studies for Accurate® Multi Panel Drug Urine Test cup were performed in-

house with three operators.

Operators ran 80 (40 negative and 40 positive) unaltered urine samples. The samples were blind

labeled and compared to LC/MS or GC/MS results. The results are presented in the table below:

Lay-user study:

184 males and 126 females tested Accurate® Multi Panel Drug Urine Test Cup Configuration 1

(including MOP 300); 178 male and 132 females tested Accurate® Multi Panel Drug Urine Test Cup

Configuration 2 (including MOP 2000 (OPI). They had diverse educational and professional

backgrounds and fluent in English and their age range from 20 to over 50. Urine samples were

prepared at the following concentrations; -100%, +/-75%, +/-50%, +/-25% of the cutoff by spiking

drug(s) into drug free-pooled urine specimens. The concentrations of the samples were confirmed by

LC/MS. Each sample was aliquoted into individual containers and blind-labeled. Each participant

was provided with the package insert, 1 blind labeled sample and a device. The results are

summarized below.
